Things To Do on an eBike in Mercer County
One route dominates Mercer County, and it is a good one: the Delaware and Raritan Canal towpath, roughly seventy level and largely car-free miles of linear state park running straight through Princeton, along Lake Carnegie, and south toward Trenton. The surface is mostly crushed stone rather than asphalt, which matters for tyre choice.
Around it sit Princeton Battlefield, Washington Crossing State Park on the Delaware, Grounds For Sculpture in Hamilton, and the Sourland hills northwest. Below: the named routes, day itineraries, the state park rules that apply, and seasonal timing.
Where to ride an eBike in Mercer County
One route dominates this county, and it is a good one. The Delaware and Raritan Canal towpath runs roughly seventy level miles through Delaware and Raritan Canal State Park -- a linear park following an 1830s freight canal from the Delaware River across central New Jersey. It passes straight through Princeton, runs the length of Lake Carnegie, and continues south toward Trenton.
It is flat and largely car-free, but the surface is predominantly crushed stone rather than asphalt, which matters for tyre choice. Around the corridor sit Princeton Battlefield, Washington Crossing State Park on the Delaware, Grounds For Sculpture in Hamilton, and -- for anyone wanting hills -- the Sourland Mountain country northwest around Hopewell.

Named eBike routes in Mercer County
These are the rides worth planning a day around. Distances are approximate and assume you start from Princeton or the nearest towpath access.
1. The D&R Canal towpath (10-40+ miles)
The spine of riding here. The Delaware and Raritan Canal was dug in the 1830s to move freight between the Delaware and the Raritan, and its towpath is now roughly seventy level miles of linear state park. North from Princeton it runs past the lock at Kingston toward Rocky Hill and eventually Raritan; south it follows Lake Carnegie toward Trenton. Flat, shaded, largely car-free -- with a crushed stone surface that rewards wider tyres. Shops: eBike shops in Princeton NJ.
The D&R Canal towpath: seventy level miles of linear state park across central New Jersey.
2. Lake Carnegie and the Princeton campus (6-14 miles)
South of the university the towpath runs the length of Lake Carnegie -- the artificial lake Andrew Carnegie funded in the early 1900s so the Princeton crews would have somewhere to row. Pair it with a slow lap of the campus: Nassau Hall, which briefly housed the Continental Congress in 1783, the chapel, and the quadrangles. Compact, busy, and best ridden gently.
The campus is compact and busy -- ride it slowly, and stop for Nassau Hall.
3. Princeton Battlefield and the 1777 ground (8-14 miles)
Princeton Battlefield State Park on Mercer Road preserves the field where Washington defeated British regulars in January 1777, days after the Delaware crossing and the victory at Trenton. The Clarke House and the Colonnade stand on the ground. Flat, easy, and it connects naturally back to the canal.
4. Washington Crossing and the Delaware (20-35 miles)
Northwest of Trenton, Washington Crossing State Park marks where the Continental Army crossed the Delaware on Christmas night 1776. The canal feeder and the river run together along this stretch, giving a long quiet corridor with the Delaware on one side. State park land with its own electric bike rules.
The Delaware at the crossing -- the canal feeder and the river run together here.
5. Trenton, the State House, and Grounds For Sculpture (18-30 miles)
South down the corridor to Trenton, the state capital, with the New Jersey State House -- among the oldest state capitols in continuous use in the country -- the Trenton Battle Monument, and the Delaware riverfront. East in Hamilton, Grounds For Sculpture is forty-two acres of monumental contemporary sculpture on a former fairground. Ride there, then walk it. Shops: Trenton eBike shops.
Grounds For Sculpture in Hamilton: ride there, then walk it.
6. The Sourlands and Hopewell (20-35 miles)
The county's hills, and its one real exception. The Sourland Mountain country northwest around Hopewell is a large block of forested ridge -- genuinely steep in places, quiet, and a completely different sport from the towpath. Baldpate Mountain and Rosedale Park sit on the way out. Shops: Hopewell eBike shops.
Half-day and full-day eBike plans
Half day (2-3 hours), the easy classic: The towpath south from Princeton along Lake Carnegie and back, with a slow lap of the campus. Six to twelve flat miles and the best first ride in the county.
Half day, history: Nassau Street and the university, out Mercer Road to Princeton Battlefield, and back via the canal. Short, flat, and dense with 1777.
Full day, capital run: The towpath south to Trenton for the State House and the riverfront, out to Grounds For Sculpture in Hamilton, and back. Twenty-four to thirty-two miles on level ground. Riders doing consecutive long days sometimes keep a portable power station for eBike day trips at home for an overnight top-up.
Full day, the crossing: Northwest along the canal feeder to Washington Crossing State Park and the Delaware river road, returning through Ewing or Hopewell. Twenty-five to thirty-five miles with the option of adding Sourland climbing.
The rules that actually matter here
New Jersey treats low-speed electric bicycles -- broadly Class 1 and Class 2, pedal-assist and throttle up to 20 mph -- much like ordinary bicycles, with no license, registration, or insurance required. Faster Class 3 style machines are a separate legal category with additional requirements.
Because so much of the riding here is on one piece of land, Delaware and Raritan Canal State Park is the rule that matters most -- it governs the towpath along its full length and sets its own policy on electric bikes. Princeton Battlefield and Washington Crossing are separate state parks with their own rules, Mercer County parks post their own signage, and the Princeton campus is private property with its own expectations about riding. The other practical constraint is not legal at all: the towpath surface is crushed stone and it goes soft after heavy rain.
When to ride Mercer County
April through June and September through early November are the best windows, with October on the towpath particularly good. Avoid the days right after heavy rain, when the crushed stone turns soft and puddled. Summer is humid but the towpath is shaded for most of its length. Winter riding works when the surface is firm, and Washington Crossing in late December has an obvious appeal.
Frequently asked questions
What is the best eBike route in Mercer County?
The Delaware and Raritan Canal towpath, in either direction from Princeton. North it runs toward Kingston, Rocky Hill, and eventually Raritan; south it follows Lake Carnegie and carries on toward Trenton and the Delaware. Roughly seventy level, largely car-free miles in total, and the single best long-distance ride in central New Jersey.
Is the canal towpath paved?
Mostly not. The towpath is predominantly crushed stone and packed dirt rather than asphalt, which is fine on wide tyres and unpleasant on narrow ones, and it can be soft or puddled after heavy rain. As Delaware and Raritan Canal State Park land it also sets its own rules on electric bikes, so check current policy before planning a long ride.
What is at Washington Crossing State Park?
It marks the New Jersey side of the Delaware crossing on Christmas night 1776, when the Continental Army crossed the river and marched on Trenton. The park sits on the Delaware northwest of Trenton with the canal feeder alongside, and it connects naturally into a towpath day. It is state park land with its own rules on electric bikes.
Is Mercer County hilly for biking?
Mostly no. The canal corridor, Princeton, Trenton, and the county parks are essentially flat. The exception is northwest, where the Sourland Mountain country around Hopewell is a forested ridge that is genuinely steep in places -- a completely different ride from the towpath and the reason some riders here want assist at all.
What is Grounds For Sculpture?
It is a forty-two-acre outdoor sculpture park in Hamilton, built on a former state fairground, with monumental contemporary sculpture set among specimen trees and water features. It is one of the better destinations in central New Jersey, though it is a walk-in place once you arrive rather than somewhere you ride through.
Where can I buy or service an eBike in Mercer County?
Lawrence Township holds the county's dedicated electric bike shop at 4.9 across 118 reviews, plus an REI at 409 reviews. Princeton has a long-standing shop at 4.7 across 340 reviews and a rental listing. Hightstown, Trenton, Hopewell, Lawrenceville, Ewing, Mercerville, Robbinsville, and East Windsor each add a shop.
